Much better:

I forgot to write, that a similar problem was observed in FreeBSD 7 with
usb4bsd patches.

Yes, I have AMD platform (motherboard ASUS A8N-VM-CSM)

Yes, I have already posted the result - 22 Mb/sec, much better

Today, I tested another flash drive
ugen1.2: at usbus1
umass0: on usbus1
umass0: SCSI over Bulk-Only; quirks = 0x
umass0:3:0:-1: Attached to sc
This flash drive works fine on another system (Intel 6300ESB USB 2.0
controller) with FreeBSD-8-current.
May be problem in controller?
